Dynamic Binding which is also known as Late binding or run-time binding, is a process of executing the part of the code at runtime. Object Oriented Programming Objective type Questions and Answers. Chapter 4. Its utilized to break down a software program into reusable code blueprints (called classes) that you may use to build specific instances of things. These objects are organized into classes where individual objects can be grouped together. It is like a blueprint of an object. It enables a class to acquire or get the properties from another class, It makes easier to add new features or methods to a class, It provides an overriding feature which allows a child class to have a specific implementation of a method defined in the parent class, A class that is inherited by other classes is termed as super class or parent class or base class, whereas a class that extends another class is termed as sub-class or child class, Inheritance can be classified into majorly 5 types : Single Inheritance, Multilevel inheritance, Hierarchical Inheritance, Multiple Inheritance and Hybrid Inheritance. 15)ArrayList is a part of which of the following sub packages?

Inheritance -. apart . Classes can be used to implement Abstraction in C. Using available access specifiers, class allows us to group data members and member functions. Which feature of OOP indicates code reusability? Code reuse is the use of existing software to build new software. The attributes specified in the class may have unique values for each object. These functions are specified inside the class and execute an action beneficial to that particular object type. APIs provide a mechanism to enable code reuse. LIVE Course for free.
